INTRODUCTION

Briggs and Stratton has made every effort to provide for a

safe, streamlined and cost-effective installation. Because

each installation is unique, it is impossible to know of and

advise the trade of all conceivable procedures and methods

by which installation might be achieved. Neither could we

know of possible hazards and/or the results of each

method or procedure. For these reasons,

Only current qualified electrical contractors

should attempt HGS Installations.

Installations must strictly comply with

all applicable codes, industry standards

and regulations.

Your Briggs & Stratton Home Generator System is supplied

with this “Owners Manual” and a separate “Installation

Manual” (part number 190854).These are both important

documents and should be retained by the owner after the

installation has been completed.

WARNING! Per National Electric Code,

connection of a generator to any electrical circuit

normally powered by an electric utility must be by

means of approved transfer switch equipment so as

to isolate the electrical circuit from the utility

distribution system when the generator is operating.

Failure to isolate the electrical circuits by such

means may result in injury or death to utility power

workers due to backfeed of electrical energy.

The semi-automatic transfer switch is suitable for use in

accordance with Article 702 of the National Electric Code,

ANSI/NFPA 70.This switch is suitable for use on a circuit

capable of delivering not more than 10000A RMS,

symmetrical current, 120/240V, when installed on the load

side of appropriate branch circuit. For indoor use only.The

connection box is a NEMA type 3R, intended for outdoor

use.

Essential Circuits

As a Home Generator System owner, it is important that

you clearly identify the circuits in your building that are

"essential" to you.Your Home Generator System is

equipped with a Semi-Automatic

Transfer Switch.When

properly wired, your selection of essential circuits will be

transferred to the generator power within 10 seconds

(+/- 5 seconds) after the generator is connected and started.

It is important that your installer understand which

circuits

you want to include as "Essential Circuits". Depending on

the power consumed by these circuits, most or all of them

can be switched to the Home Generator System for the

duration of normal power interruption.

The wattage reference guide shown in Figure 3 will assist

you with your decision-making process. It provides the

wattage used by many ordinary household devices. Use it as

a guide when selecting your essential circuits. Review this

information with your installer and ask about any technical

considerations that might affect the cost of your installation.

Essential Circuit Selection

When selecting the essential circuits that will be switched to

“Backup Power,” it is important that the sum of the combined

circuit loads does not exceed the wattage/amperage capacity

of the generator.To help you with your selection of essential

circuits, please consider the following:

Add up the total wattage of all electrical devices to be

connected at one time.This total should NOT be

greater than the generator’s wattage capacity.

The rated wattage of lights can be taken from light bulbs.

The rated wattage of tools, appliances and motors can

usually be found on a data plate or decal affixed to the

device.

If the appliance, tool or motor does not give wattage,

multiply 120 Volts times the ampere rating to determine

Watts (Volts x Amps = Watts).

Some electric motors (induction types) require about

three times more watts of power for starting than for

running.This surge lasts for only a few seconds. Be sure

you allow for this high starting wattage when selecting

electrical devices that will be energized by the Home

Generator System:

Figure the watts required to start the largest motor.

Add that to the total running watts of all other

connected loads.

BEFORE INITIAL START-UP

Add Oil

CAUTION! Any attempt to crank or start the engine

before it has been properly filled with the recommended

oil may result in an engine failure.

To fill your engine with oil:

• Place generator on a level surface.

• Follow the oil grade recommendations and oil fill

instructions given in the engine owner’s manual.

NOTE: The generator’s revolving field rides on a

prelubricated and sealed ball bearing that requires no

additional lubrication for the life of the bearing.

Add Gasoline

WARNING! Never fill fuel tank indoors. Never

fill fuel tank when engine is running or hot.Allow unit

to cool for two minutes before refueling. Do Not

light a cigarette or smoke when filling the fuel tank.

WARNING! Do Not overfill the fuel tank.

Always allow room for fuel expansion.

• Use regular UNLEADED gasoline with the generator

engine. Do Not use premium gasoline. Do Not mix oil

with gasoline.

• Clean area around fuel fill cap, remove cap.

• Slowly add unleaded regular gasoline to fuel tank. Be

careful not to overfill.Allow about 1.5" of tank space for

fuel expansion (Figure 6).

• Install fuel cap and wipe up any spilled gasoline.

IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts, such as the

carburetor, fuel filter, fuel hose or tank during storage.Also,

experience indicates that alcohol–blended fuels (called

GROUNDING THE

GENERATOR

The National Electrical Code requires that the frame and

external electrically conductive parts of this generator be

properly connected to an approved earth ground. Local

electrical codes may also require proper grounding of the

unit.Whenever the unit is connected to the system’s

properly installed power inlet box, the generator is

automatically connected to the building’s grounding system.

IMPORTANT: When operating the unit as a stand-alone

generator, the unit should

be connected to a grounding

rod, especially when the unit is equipped with a wheel kit.

Properly grounding the generator helps prevent electrical

shock if a ground fault condition exists in the generator or

in connected electrical devices. Proper grounding also helps

dissipate static electricity, which often builds up in

ungrounded devices.

A GROUNDING WING NUT is provided (Figure 7) to

make the grounding attachment.

Connecting a No. 12 AWG (American Wire Gauge)

stranded copper wire to the grounding wing nut and to an

earth–driven copper or brass grounding rod (electrode)

provides adequate protection against electrical shock.

CAUTION! Do Not connect the unit to a

grounding rod at the same time it is connected to

the building’s power inlet box.

OPERATING THE

GENERATOR

CAUTION! Never start or stop unit with

electrical loads connected AND with the connected

devices turned ON.

IMPORTANT: Always unplug the battery float charger

before starting the generator.

Starting the Engine

Disconnect all electrical loads from the generator. Use the

following start instruction steps by numerical order:

1. Move the fuel valve to the “On” position (Figure 8).

2. To start a cold engine, move the choke lever to the

“Choke” position. To restart a warm engine, leave

the choke lever in the “Run” position (Figure 9).

3. Set the rocker switch to the “On” position (Figure 10).

• Do Not connect 240 Volt loads to the 120 Volt

receptacles.

• Do Not connect 3–phase loads to the generator.

• Do Not connect 50 Hz loads to the generator.

• DO NOT OVERLOAD THE GENERATOR. When

not used with the semi-automatic transfer switch, add up

the rated watts (or amps) of all loads to be connected at

one time.This total should not be greater than the rated

wattage/amperage capacity of the generator. See “Don’t

Overload the Generator” on page 14.

Stopping the Engine

• Unplug all electrical loads from generator panel

receptacles. Never start or stop engine with electrical

devices plugged in and turned on.

Briggs & Stratton Power Products Home Generator System

Owners Manual

This receptacle powers 120/240 Volt AC, 60 Hz, single

phase loads requiring up to 3600 Watts of power at

30 Amps for 120 Volts; 6500 Watts of power (6.5 kW) at

27.1 Amps for 240 Volts.The outlet is protected by a

30 Amp circuit breaker.

CAUTION! Although this outlet states it has a

240 Volt 30 Amp rating (up to 7,200 Watts), the

generator is only rated for 6,500 Watts. Powering

loads that exceed the wattage/ amperage capacity of

the generator can damage it or cause serious

injuries. 240 Volt loads powered through this outlet

should not exceed 27.1 Amps of current draw.

Light

A light is provided on the control panel to assist movement

in the dark.Turn on the light using the switch on the

control panel.

Always turn off the light when not needed as it drains the

generator battery.Turn off the light when the generator is

running.

How to Use the Battery Charger

Use the battery float charger jack to keep the starting

battery charged and ready for use. Battery charging should

be done in a dry location, such as inside a garage.

• Plug the charger into the unit’s “12V DC Float Charger”

jack, which is located on the control panel (Figure 13).

Plug battery charger into a 120Volt AC wall receptacle.

• Unplug the charger from the unit and the wall outlet when

generator is being started and while it is in operation.

• Keep this charger plugged in when generator is not in

use to prolong battery life.The charger has a built in float

equalizer and will not overcharge the battery, even when

plugged in for an extended period of time.

IMPORTANT: See “Battery Maintenance” on page 17 for

additional information.

Hour Meter

The hour meter operates whenever the unit’s engine runs.

Use the hour meter to plan service tasks mentioned in the

engine owner’s manuals.

DON'T OVERLOAD YOUR

GENERATOR

NOTE: Refer to this section when you are using the

generator without the semi-automatic transfer switch.Ask

your semi-automatic transfer switch installer to review load

management techniques. See “Essential Circuits” on page 6.

Capacity

You must make sure your generator can supply enough

rated (running) and surge (starting) watts for the items you

will power at the same time. Follow these simple steps:

1. Select the items you will power at the same time.

2. Total the rated (running) watts of these items.This is

the amount of power your generator must produce to

keep your items running. See Figure 14.

3. Estimate how many surge (starting) watts you will

need. Surge wattage is the short burst of power

needed to start electric motor-driven tools or

appliances such as a circular saw or refrigerator.

Because not all motors start at the same time, total

surge watts can be estimated by adding only the

item(s) with the highest additional surge watts to the

total rated watts from step 2.

Example:

Total Rated (Running) Watts = 3075

Highest Additional Surge Watts = 1800

Total Generator Output Required = 4875

Power Management

To prolong the life of your generator and attached devices,

it is important to take care when adding electrical loads to

your generator.There should be nothing connected to the

generator outlets before starting it's engine.The correct

and safe way to manage generator power is to sequentially

add loads as follows:

1. With nothing connected to the generator, start the

engine as described in this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly.

4. Plug in and turn on the next load.

5. Again, permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load.

Never add more loads than the generator capacity.Take

special care to consider surge loads in generator capacity,

as described above.

*Wattages listed are approximate only. Check tool or

appliance for actual wattage.

OPERATING THE POWER

TRANSFER SWITCH

Switch To Generator Power

To switch to generator power after a utility power failure:

1. Align the female socket of the power cord with the

connection box receptacle’s mating male prongs, as

shown in Figure 15. Push power cord connector in and

twist clockwise to lock.

2. Align the male prongs on the other end of the power

cord with the mating female terminals of the

generator’s 240V receptacle, as shown in Figure 16.

Push in connector and twist clockwise to lock.

3. Ensure generator is outdoors and fluids and fuel are

topped-off.

4. Open the main circuit breaker on the generator

control panel. Start the generator using instructions

given in the section “Operating the Generator” on

page 11.

5. Close the generators main circuit breaker.

6. After a ten second delay, the transfer switch will

transfer essential circuit loads to the generator.

Load Management

The number of circuits that can be operated simultaneously

during a utility failure will depend on the wattage capacity of

your generator. Most portable generators do not have

the capacity to handle loads on all circuit breakers

at the same time.

Review the load management plan developed with the

installer (see “Plan the Installation” in the Installation

manual, P/N 190854). It may be necessary to selectively turn

on and off certain loads while using generator power so

that necessary appliances can be operated safely.

GENERAL MAINTENANCE

RECOMMENDATIONS

The Owner/Operator is responsible for making sure that

all periodic maintenance tasks are completed on a timely

basis; that all discrepancies are corrected; and that the unit

is kept clean and properly stored. Never operate a

damaged or defective generator.

Engine Maintenance

See engine owner’s manual for instructions.

CAUTION! Avoid prolonged or repeated skin

contact with used motor oil. Used motor oil has

been shown to cause skin cancer in certain

laboratory animals.Thoroughly wash exposed areas

with soap and water.

KEEP OUT OF REACH OF CHILDREN. DON'T

POLLUTE. CONSERVE RESOURCES. RETURN

USED OIL TO COLLECTION CENTERS.

Generator Maintenance

Generator maintenance consists of keeping the unit clean

and dry. Operate and store the unit in a clean dry

environment where it will not be exposed to excessive

dust, dirt, moisture or any corrosive vapors. Cooling air

slots in the generator must not become clogged with snow,

leaves or any other foreign material.

NOTE: Do Not use a garden hose to clean generator.

Water can enter engine fuel system and cause problems. In

addition, if water enters generator through cooling air slots,

some of the water will be retained in voids and cracks of

the rotor and stator winding insulation.Water and dirt

buildup on the generator internal windings will eventually

decrease the insulation resistance of these windings.

Battery Maintenance

Other than float charging, described elsewhere, no

maintenance is required for the battery. Keep the battery

and terminals clean and dry.

IMPORTANT: Battery charging should be performed in a

dry location, such as inside a garage.

To Clean the Generator

• Use a damp cloth to wipe exterior surfaces clean.

• A soft bristle brush may be used to loosen caked on dirt

or oil.

• A vacuum cleaner may be used to pick up loose dirt and

debris.

• Low pressure air (not to exceed 25 psi) may be used to

blow away dirt. Inspect cooling air slots and opening on

generator.These openings must be kept clean and

unobstructed.

18

Briggs & Stratton Power Products Home Generator System

Owners Manual

STORAGE

The generator should be started at least once every seven

days and allowed to run at least 15 minutes. If this cannot

be done and you must store the unit for more than 30 days,

use the following guidelines to prepare it for storage.

Generator Storage

• Clean the generator as outlined in “To Clean the Generator.”

• Check that cooling air slots and openings on generator
